LXX Num 9:13

καὶ ἄνθρωπος ὃς ἐὰν καθαρὸς ᾖ καὶ ἐν ὁδῷ μακρᾷ οὐκ καὶ καὶ ὑστερήσῃ ποιῆσαι τὸ πάσχα, ἐξολεθρευθήσεται ἡ ψυχὴ ἐκείνη ἐκ τοῦ λαοῦ αὐτῆς· ὅτι τὸ δῶρον κυρίῳ οὐ προσήνεγκεν κατὰ τὸν καιρὸν αὐτοῦ, ἁμαρτίαν αὐτοῦ λήμψεται ὁ ἄνθρωπος ἐκεῖνος.

But if a man who is ceremonially clean and is not on a journey still fails to observe the Passover, he must be cut off from his people, because he did not present the LORD’s offering at its appointed time. That man will bear the consequences of his sin.
